Position Sizer

Managing risk is the number one discipline in trading. Without it, the market will eventually wipe out your account — but a disciplined approach to risk management minimizes the impact of any single bad trade.

Position Sizer calculates exactly how many shares or units you can buy or sell, based on the maximum percentage of your account you're willing to risk.

How it works:

Set your stop loss — just beyond the recent local dip (long) or local peak (short).
Enter your account size, stop loss, entry price, and the risk % you're willing to take (2% is a commonly recommended maximum per trade).
The calculator instantly gives you your position size, along with a 5R take-profit target (5× your risk).
Long-press any value to copy it, then paste it straight into your broker's order form.
Features:

Instant position size, risk amount, and position value calculations
5R take-profit target, calculated automatically
Long-press any value to copy it to your clipboard
Clean, distraction-free interface built for fast entry
All data stays on your device — nothing is transmitted anywhere
